There are skins for the West Coast Racing BMWs, Engstrom's Honda from last year and last year's Peugeot over at nogrip (I think the Pegueot is in the R-Factor downloads section and I had to create an ini file for it), which I have been using with the Flash BMWs until the STCC addon is released.
I've been searching for 2008 STCC Honda skins, but not had any luck. I attempted trying to create the skin, by using one of the original Thompson WTCC Honda skins from when they were testing with the 2006 Honda as a template and painting over the top, as the red and black bits are reversed for the STCC cars, but that was less than successful, so I gave up.:frown:
